Similar reference characters indicate the same or similar parts in all the figures.

I will first describe the mechanism for forming the blanks. which mechanism is lo catcd near the ca .1 1 of the machine shown in Fig. E2.

a carrier 31 is mounted to slide horizontally in an opening 36 formed in the bed or table of the machine (see Figs. .3, 6, 7 and 23), said carrier having means for heating the tipforming devices hereinafter described. The lower part of said carrier is formed a cylindrical box like structure adapted to contain a vsuitable hiater such a an electric heater indicated conventionally at- 32 in Fig. 5. the wires of the circuits for such heater being indi :ated at 33 (see also Fig. 4). The carrier 3t supports and moves certain elements of the tip forming mechanism hereinafter described, which mechanism severs a tip blank a from the strip 0 of celluloid. wraps said blank in tubular form around the ribbon I), welds the longi tudinal and lapped edges of the blank together to provide a. permanent tube (1 which, as indicated in Figs. 12 and 13, is of double the length of a lacing tip, it. being understood that by mechanism hereinafter described, the tube and the lacing fabric or ribbon therein is severed to form the tipped ends of two laces.

The frame of the maehlne supports :1

shaft 34 (Fig. 5) having a cam 38 that actuates the carrier 31 in one direction by means of a trundle roll 39 carried by a vertical slide 40, the upper end of which is connected by a link 44 with an arm 4.5 of a rock shaft 46, said rock shaft having another arm 47 connected by a link 48 to an car 49 of the carrier 3 'llhe link 48 is preferably adjustably connected with said ear, as indicated by dotted lines in Fig. 5, to enable the proper position of the carrier to be readily secured. vertical slide 40, and consequently of the carrier 31. also, may be effected by an internal cam 41 on shaft 34 engaging a roll 42 projecting laterally from slide 40.

The tip-forming mechanism includes elements supported above the carrier 31 by a frame standard 37.. rising above the table Mounted in said standard is a vertical slide 50 carrying ashear blade or knife 51 which cooperates with a cutting edge 52 (see Fig. 23) on the carrier in severing a blank from the strip a. The slide 50 also arries a primary folding blade or crimper 53 formed to cooperate with opposed faces on parts upported by the carrier 31 in imparting to the blank a trough shape, prelin'iinary to the placing of the ribbon in the trough.

Mounted in the standard 37, parallel with the slide 50 is anoth slide 54 which carries a secondary folding blade or punch which has a grooved lower edge 56 (Figs. 5, l and 23) adapted and operated as hereinafter de scribed to first bend one edge of the edges of the trough-shaped blank inwardly as shown in Fig. i i and afterward bend the opposite edge of the blank inwardly as shown inFig. 25, the tube which is thus completely formed having its edges slightly overlapped. 'lhe means for actuating the slides 50 and 54 will be described presently. They are reciprocated vertically in guides in the standard 37, located over the path in which the carrier 31 reciprocates horizontally, so that the knife 51, crimper 53 and punch are adapted to cooperate successively with the parts of the tip-forming mechanism mon'nted on said carrier.

hen the slide 50 first descends. the knife ill coacts with the cutting edge 52 and cuts oil a blank which is immediately pushed into the recess presently described, by the crimper 53 (Fig. 23). As the slide rises, the end of the strip springs back to horizontal position ready to be fed forward over the edge 52. One side of the channel or recess into which the blank is pushed is formed by the rear face 60 of a vertical flange 58 (Figsp23 and 26) rising from the canrier 31, the cutting edge being an an ular corner of said flange. The other si e of said recess is formed by the end 61 of a slide 62 (Figs. 23 and 27) which is movable horizontally on the car- The return motion of the rier. Said channel or recess is indicated at 64 in Figs. and 7. The slide 62 s normally retained in the position shown in F 1g.

\ 23 by a spring 63, one end of spring 'recess or channel is of maximum width and is positioned to receive the lower portion of the crimper 53, thecutting edge 52 being positioned to cotiperate with the knife 51.

' The carrier remains in this position While the slide descends and causes the severance of a blank from the strip and the insertion of said blank in the channel '64 by the erimper 53, the blank being given a troughshape by the sides of the channel and said crimper. The slide 50 then rises and the carrier is moved outwardly to the position shown in Fig. 24, the channel being now under the punch 55, and the channel face 61 substantially in alinement with the outer side ofsaid punch. \Vhil'e the carrier is in this position the ribbon is deposited in the bent blank by the mechanism hereinaft r described. Such. deposit occurs before the punch descends to the position shown in Fig. 24. When said punch descends it enters the channel at one side of the center thereof so that its grooved lower edge engages one of the lips or edges of the bent blank and rolls said lip over upon the ribbon. The slide 54 isthen raised and the carrieris given a slight further outward movement, but the slide 62 has made contact with the fixed stop 66 so thatthe face is moved toward the face 61 resulting in decreasing the width of the channel, the face 60 being now substantially in alinement with the inner side of the punch 55. The slide- 54 now again descends and engages the other lip of the partially folded blank (Fig. 25) rolling it over upon the previously rolled lip and completing the formation of the tube. These operations can be effected without liability of the first-rolled lip springing up before the other lip is rolled down, because the members which operate directl on the bla nkare all kept warm by the heater so that-the resilience of the sheet material is temporarily non-existent. 42

Prior to cach descent of 'the punch 55, a small quantity of alcohol or other liquid which is a solvent or softener of the celluloid or other equivalent sheet material, is discharged upon said punch in a manner so that it will flow to and along the entire lower edge of the punch and act to soften the portions of the blank with which said edge comes in'contact. Said solvent or s'of- 55 tener is supplied through a duct 67 (Figs.

6 and 21), said duct communicating with a. cup or small vertical boring 68 in the standard 87, which is ntermittently charged with the liquid from a reservoir 69 by automatic means hereinafter described, the duct (37 being provided with a needle valve 70 which is opened by the ascent of the punch 55, and allows a small quantity of the liquid to flow to said punch and down to and along its lower edge. This softening of the tip material, together with 4 the pressure exerted upon it by the punch, and the heat imparted to the faces 60, 61, as well as to the punch by the heater, insures the formation of a permanent tube which tightly embraces the inclosed and compressed ribbon fabric. Since the entire lower edge of the punch is supplied withsolvent or softening material, when said punch descends the liquid, owing to its own consistency and its aflinity for celluloid, spreads over the entire inner surface of the sheet material so that the heat, and the pressure of the final act of wrapping, result in the inner surface portions of the sheath or tube uniting with the fibers of the ribbon fabric with such intimacy as to hold 'the tip tightly on the lacing when in use, with out any necessity of perforating or Other wise rendering the .tube irregular. The fibers of the ribbon are to someextent embedded in the inner surface of the tube, and the overlapped edges or lips of the blank are so intimately united that the final sheath or tip is practically seamless or integral throughout, and capable of withstand ing' all pulling strain, and the effort of the inclosed fabric to expand from an extremely compressed and small condition.

Before describing the mechanism for severing the sheath and the inclosed ribbon, I will explain the means for actuating the slides 50 and 54. The slide 50 which carries the knife and crimper is formedwith recesses in its sides (Fig. 5.) to i'eceive the forked end 71 of a lever 72 (Figs. 2 and 21) pivotally mounted on a screw or bolt 73 and having its outerend provided with a pin 74 to which a spring 75 is connected to cause said lever to follow the movements of a vertical slide 76, the outer end of the lever hearing on the top of said slide as shown in' Fig. 2. The lower end of said slide is shown in Fig. 5, and has a roll 77 bearing on a cam 78 secured on shaft 34. The slide v54; 'is connected by a link 7 9 (Fig. 5) wit-h a lever 80 pivoted at 81 (Fig. 6) in the standard 37. The,pivotpin projects as, shown in Figs. 1, 2 and '5, and a spring 82 is fixed at one end to said pin and at the other end bears on a pin 83 projecting from the lever 80, to cause said lever to follow the movements of a 'vertical slide 84 (Figs. 5 and 6) the lower end of which has a roll 85 bearing ona cam 86 secured to shaft 34. A spring-'87 depresses said slide after the cam raises it.

namely; to first roll or bend one lip of the d blank and then roll or bend the other lip v and lap it upon the first.

,The strip a of sheet celluloid or analogous material, is supplied from a reel 88 (Fig. 2) supported by brackets 89, and passes over .the tablebetween suitable guides 90, to the nip of the feed rolls 91 which are geared together at 92. To actuate these rolls stepby-step to advance the strip in a direction toward the right, Fig. 23, I provide the following mechanism. A ratchet 93 (Figs. 2, 4,18 and 19) issecured to the shaft 94 of the lower feed roll. Hung on shaft 94 is a lever 95 having two pawls 96, 97 spring-pressed toward the ratchet. A link or connecting rod 98 is connected atone end to the lever.

(Fig. 4) so that as said carrier reciprocates for each operation, the strip a is advanced one step. To vary the length of feed to control thearea of the blanks severed from the strip according to the bulk of the lacing ribbon, I provide a shield 99 carried by an arm 100 which is pivoted on shaft 94, said shield having a rod or ,arm 101 connected to it, the other end of said arm having a slot 102 (Fig. 2) through which a binding or set screw 103 passes into the table 35. By adjnsting the setting of the arm 101, more or less of the shield is interposed between the ratchet and the path of reciprocations of the pawls so that feed movements of any desired extent may be imparted tothe rolls 91.

The ribbon fabric 6 is supplied. from a suitably mounted reel. 101,'and passes over the table 35 and under a spring pressed tension bar 105 (Figs. 1, 2 and 6), then under the punch 55 and between folders to turn the edges of,thc'ribbon inwardly as herein- 95 and at the other end to the carrier 31 after described, then between a pair of feed rolls 106. then. under an adjustable roller 107, then between asecond pair of feed rolls 108, and thenbetween a third pair of feed rolls 109, which latter push the ribbon and the tube thathas been a; nlied thereto, under the knife 110 carried b a bar 111, which knife completes the format. 111 of the tipped laces. The purpose'of the oller 107 is to form a loop or bight in thcrinbon toprovidc for proper lengths of lacings ithout having to space the knife which cuts the tubes sofar from the place where the said tubes are applied, as is necessary when the ribbon is drawn straight out from the forming mechanon illustrated in said Figs. 28, 29 and 30,- since the only advantage resulting friim the bight-fortning roller 107 is the saving of a couple of .feet or so in the length of the machine.

Before describing the'construction illustrated in. said Figs. 28, 29 and 30, I will refer to the mechanism which is the same in both forms of machine illustrated in the drawings, and therefore, for the present, no reference need be made to the said Figs. 28, 29 and 30. Referring to Fig. 6, the two -rolls of each of the pairs 106, 108 and 109 are geared together, and all are intermittently rotated in a direction to feed the ribbon toward theleft in said Fig. 6. The loop or bight-forming roller 107 is mounted on a rod 112 (Fig. 3) the ends of which pass through inclined slots 113 in the sides of the frame (see Figs. 1 and 6). Mounted on the rod 112 at each end thereof isa hub 114 which is yieldingly pressed toward the inside of the frame by a spring 115 confined between the inner end of the hub and a collar 116 secured to said rod. The hubs 114. have pins 117 projecting from their faces, said pins being adapted to enter any one of the pairs of holes 118 formed in the frame at the sides. of the slots 113. When longer or shorter lacings are to be formed, the rod 112 carrying the roller 107 is adjusted along the slots- 113-' by grasping the hubs 1145, drawing them toward each other to release their pins 117 from the holes 118, then sliding the rod and its hubs toward the desired position, after which the hubs may be released and if the pins do not then enter holes the rod may be moved a little farther in the desired direction and the pins will snap into the holes so that the roller 107 will remain in the desired position according to the length of lacings that are to be tipped. The intermittent rotation of the first two pairs of feed rolls 106, 108, is obtained by a gear 119 (Fig. 6) mounted on a shaft 120, which is intermittently actuated as hereinafter described, said gear 119 meshing with the pinions on the lower rolls of said two pairs. The rolls 109 are driven at a slightly higher surface speed than that of the rolls 106, 108, to constantly preserve a tension upon the ribbon. As will be presently described, however, the surfaces of the rolls 109 may slip upon the celluloid tube when the latter reaches the nip of this pair of rolls and is stopped by the gage in position for the operation of the knife. The rate of speed of the rolls 109 is about ten per cent. faster than that of the rolls 106,108. the drive of said rolls 109 being effected by a train of gearing 121, 122, 123, and 121, the pin on or gear 121 being driven by the pinion of the lower roll of the pair 108, while the pin ions .or gears 123, 124, are compounded, the smaller one 123, meshing with the intershaft 127 is a pinion 132 having clutch teeth mediate gear 122 while the larger one 124 meshes with the pinion carried by the lower roll of the pair 1.09. The shaft 120, besides carrying the gear 119, has another gear 125 at its outer end, as shown in Figs. 1 and 3. Said gear 125 meshes with and is driven by a pinion 126 on a stud shaft 127 which passes through an arc slot 128 in the frame of the machine and is su 'iported by a bracket 12%) that is mounted on the shaft 31 so that it can be swung on the axis of said shaft for the purpose presently described. The inion 126 is secured to rotate with the stud shaft 127. and splined on said stud shaft is a clutch member 130 having an annular groove 13.. Mounted freely on said stud 133 so that. when said clutch teeth are engaged by the clutch member 130. the rota-- tion of the pinion 12-52 will be transmitted to the stud shaft and, through pinion 126 and gear 125, to the shaft 120, and, by the gear 119 of the latter, to the several pairs of feed rolls. A larger gear 13-1 secured on the shaft 31 meshes with the pinion 132. aid gear 34 is constantly revolved when the machine is in operation, but when the clutch member 130 is shifted away from the clutch teeth 133, the pinion 132.will r0- tate idly on the stud shaft 127 and therefore there will be no motion imparted to the shaft 120 and to the ribbon-feeding rolls.

To automatically control the clutch so that the feed will be intermittent, a yoke 135 engages the annular groove 131 of the splined clutch member, the hub 130 of said yoke being slidably mounted on a pin 137 supported by the frame of the machine. Said hub 136 has a fixed lug or pin 13 which projects into the path of a face cam 139 on the side of the gear 134. To cause the'yoke and its lmh 136 to shift on the pin 137 so that the lug 138 will follow the cam 13.) and cause the clutch 130 to be intermit tently engaged with and disengaged from the clutch teeth 133, a suitable spring 140 is employed, said spring being coiled about the stud shaft .127 andconfined between the outer face of the clutch member 130 and an arm of he bracket 129.

In order that different sizes of pinions 126 may be employed to obtain different lengths of feed of the ribbon-feeding rolls, the stud shaft 127. which is carried by the bracket 129. may be shifted along the arc slot 128. To secure the stud shaft and bracket. 12!} in adjusted position, toward or from the axis of gear 125, (Fig, 1) the bracket 13!) is provided with an arm 1 11 (Fig. (3) through whirh. and the slot 128, a clamp bolt 112 passes. The gear 131 on cam shaft 314 is driven by a pinion 143 (see Figs. 3 and t secured to a shaft 144 which carries a larger gear 145 that is driven by a pinion 146 on a shaft 147. The latter has a pulley 148 (Fig. 1) driven by a belt 149 from a. pulley 1.30 of a suitable electric or other motor 151. The sides of the frame of the machine are braced by suitable tie rods 132 (Figs. 1 and 3). J

hen the ribbon that is to be tipped is wide, it is desira le that; its edges shall be turned or folded inwardly in order that the celluloid tube shall properly inclosc it, and it is preferable that one edge shall always be folded in advance of the other. To accomplish this. I provide two pairs of folders 153, 154, (Figs. 5, 6, 7, 17 and 22), the ribbon passing between the two folders of each pair on its way to the feed rolls. In addition to these folders, which are rocked, I may employ stationary curved guides 15:) as shown by full lines in Fig. 7, and dotted. lines in Fig. 17. Each folder is mounted to oscillate on a pivot 156. and is formed with teeth 157 meshing with racks formed on vertical slide rods 1.38, 15.). There is a rack rod 158 for each of the two folders 157-3, and a rack rod 159 for each of the two folders 154. Said rank rods are actuated by arms 160 of a rock shaft 101, the latter having another arm 1112 which extends under an arm 103 of a rock shaft 101 (see Figs. 4 and 17). The rock shaft 161: has an arm 16-") (see Figs. 1 and I?) connected by a link 166 with a slide 1137 having a roll 168 bearing on a cam 1 1i} secured to shaft 34. A spring 170 coiled on rock shaft 161 and having one end secured to hearing for said shaft and the other end to a collar 171 secured oi'rthe shaft, actnates the said shaft in opposition to the cam 1139. A spring 172 coiled on rock shaft 1 31 (Figs. 1- and 22) and having one end connected to said shaft and the other end to a fixed pin 173, actuates said shaft in opposition to the arm 163 of rock shaft 161. The folder:-: 1521 and 154 are shown in Fig. 17 as in their outermost p sition, and it will be readily understood that as the rack rods 138, 159, rise, said folders will turn inwardly the, edges of any Witle ribbon that. has been drawn between them and over the channel 61 by the feed rolls. The timing of their operation is such as to do their folding just prior to the descent of the punch 55, and to remain in position to hold the ribbon folded during both of the forming operations of the punch. In order that the first descent of the punch will cause the folded ribb n (or an unfolded one if the fabrie is narrmv) to be pushed down into the trouglrshaped blank which has been previously bent into the recess or chann l (34 of the carrier by t. erimper 5 1. 1 provide a toe or presser 174- at each end of the punch 53 (l igs. 1i and 21), the parts below said toes being provided with recesses or depressions so that the lower ends of the toes can carry the ribbon at each end of the recess or channel 64 to a plane lower than the bottom of said channel, thus pressing the ribbon in taut condition into the U-shaped blank then .insaid channel. Toaccurately guide the ribbon to the folders, and to impart a ipreliminary upward turn to the extreme edges of the ribbon, I may employ adjustable guides as indicated at 175 in Figs. 2, 6 and 7. After the ribbon leaves the tubeforming mechanism, it passes under a guide 176 on its way to the rolls 106. I

I will now describe the means whereby the two folders 15 i operate in advance of the opposite folders 153 (Fig. 17) to insure proper folding of a wide ribbon. The two rack rods 158, 159, of each pair are actuated by one arm 160 of the rock shaft (see Fig. 17) and the two arms 160 are substantially alike (see Figs. 4 and 22), being formed with slots 177 through which the flattened lower ends of the rack rods pass, thus preventing the rack rods from turning on their longi tudinal axes. In Fig. 4, the slots are shown as formed in lateral projections of one arm 160 and directly in the body of the other arm 160, but this is merely due to expediency of construction and does not affect the operation. The structure shown in Fig. 17 may apply to either pair of rack rods. As'shown in said figure, the rack rods are provided with pins 178 near their lower ends,'the rod 158 has a shoulder 179, and the rod 159 has an upper pin 180 between which and the top of arm 160 a spring 18L is confined on the rod. A stop plate 182 (see also Fig. 4) extends under the lower end of each rack rod 158, to limit its lower position.

When the rock shaft 161 is a tuated so that its two arinslotl move in the direction of the arrow in F lg. 17 to elevate the rack rods and swing the folders 153, 151', to turn the edges of the ribbon the rods 1539 are lifted tirst, through the medium of the springs 18], said springs being of snlficient F str'ei'igt'h to lift the rods and rock the fold ers 154 without materially collapsing. The rods 158 do not begin to rise until the arms 160 reach the shoulders 179, but in the meantime the rods 159 have performed, or t nearly performed, their functions. After the. arms 160 l'iavc reached the shoulders; 179, further movement in the direction of said arrow causes the rods 158 to rise and rock the folders 153 inwardly. After the folders 154 have reached their inneri'nost. positions and the rods 1.59 can rise no higher, the springs 181 yield so as to permit the arms 160 to finish the actuation of the rods 158 and folders 153, thus completing the operation of uniformly folding the ribbon at the points where it is to be inclosed I in the celluloid tube. It is understood of 1 course, that during the operation of the l folders, the feeding has ceased, and that as 1 soon as the tube is applied the folders open and the feed begins and continues long enough to draw along a length of ribbon according to the length "of lacing desired, when the feed again stops and the folders act on the portion of the ribbon that is to have the next tube applied thereto.

The knife 110 which cuts through the mid-length or center of the tube and the tightly inclosed ribbon, to complete the mak ing of the tipped lacings, is carried by a bar 111 (see Fig. 20 in connection with Figs. 1, 2, 4 and 6), said bar being pivoted at 183 to a fixed bracket 18 i and at the other end guided between lugs 185. The bar 111 is connected by a link 1843 with an arm 187 of the rock shaft 104, the knife being therefore, actuated by the rock shaft at the same time that the folders are caused to collapse the ribbon at the proper point, relatively to the cut, for the length of lacing desired.

From the description so far given, it will be understood that I have provided a machine which applies to a length of lacing ribbon, at a point intermediate the ends thereof, a sheath or tube which is adapted to be cut, with the inclosed ribbon, to form two tipped lacing ends; and that by so doing I am able to produce lacings which have the tips very firmly secured thereto while the fabric is under some longitudinal tension, and, what is of especial importance, with the ends of the tips absolutely flush with the ends of the fibers inclosed therein, this being an advantage that could not be attained if two separate but adjacent tubes were applied and then only the fabric cut at a point l'iotween said adjacent tube ends. I will now describe the means whereby the tubes and the ribbmi tl'iereinl may be out at the vact center or midlength thereof to form tipped ends of two lacings, this being a pariiii'ularl v important feature of my invention. because it insures the production of lacings with tips of uniform and exact lengths. A stop 188 l-"igs. 1, 6 and 20) movable to and. froiri'i a position that is distant from the knife 1.10 equal to one-half of the applied sheath or tube and consequent ly equal to the, length of one complete tip, said stop when in position, serving to arrest the :nlvancing end of tube, the rib bon beyond said tube, being flexible, passing up over the top of the stop. The feeding movement oi the rolls does not cease until after the tube contacts with the stop,

and preferably not until just after the knife 110 has operated; ll] order that the rolls 10!), between which the rear end of the tube remains when its front end reaches the stop, may fritirtionally act on the tube to hold it against the stop while the knife operates. At this time the rolls 10E) slip on the smooth surfaca of the sheet celluloid; ,but as the upper roll is mounted in spring-pressed I bearings, the necessary friction is obtained without damage to the celluloid. means may be provided for varying the distance between the knife and the stop for Suitable 1 tips of different lengths, as by substituting f for the knife bar 111 another one having 193 (Figs. *2, t3 and 20) may be employed and to prevent the tube from being pushed over the top of said stop, a top guiding bar 194; may be used, the tip and lacing passing under said bar. Vith such a bar in place, it desirable that the stop 188 shall be lowered temporarily after the cutting of the tube in two so that the cut off lacing may drop away into any suitable re ccptacle and, in doing so, draw its rear tip out from under the bar 1951.

To intermittently supply the small receptacle 68 (Fig. 21) with solvent, a pipe 195' leads from the reservoir til) to said receptacle. the pipe having a cock 196 provided with an arm ll)? projecting into the path of movement of the pin 74 carried by the lever 72 (see Fig. 2) so that as the lever ostlllttit) the cock is intermittently opened to pcrmit small quantities of solvent to pass. The arm 1!)? is drawn against a stop screw too by a vspring; 199, to close said cock.

Whether in machine produces straight tip or tapered tips.depend. simply upon the sllupths of the cutting and forming memb rs if the tubes are to be formed as in dicated in Fig. 13, from blanks having the v hapes 'ndicatrd in Fig. lb the knife will have the form indicated at it in Fig. 9. To cooperate with one side of such knife. the table will be formed with an angular rece sed cd gc 35", and to cooperate with the other side of such knife Bl, the flange .38 will be formed with an angular re essed edge 5% (l ig. Then the faces of the members which provide the channel into which the blank is depressed by the crimper will be .-.l1ttl t(l as indicated in Fig. 8, said channel bcinp indicated at tJ-l, and the punch w ill be formed as indicated at 55 in the bottom edge view shown in Fig. 15. facilitate changes, in the shapes of the blanks cut oll', the llangc 3 may be constructed -'t'l)lll'lltt' from the carrier as indicated in Fig. 26, and attached to the can rier by any suitable means. so that one shape of flange may be vsubstituted for another.

To prevent liability of the carrier ill being thrown by its actuating mechanism, out of accurate position for the first. operation of the punch and so as to render it certain that for such operation the carrier will occupy the position shown in Fig. Z l. a suitable stop is n'ovidcd. such as the rod 200 shown in Figs. 3) and 3, said slut rod having a threaded portion engaging: a hole in the side of the frame, and having a jam not 201 to lock it in properly adjusted position.

in Figs. 38. 29 and 251'), I show means whereby the ribbon and the tubes or sheatln suc essively applied thereto, are drawn straight out. from the api'ilying and tin-tiling mechani m instead of passing down under a, bight-forming roll. The reason why it is preferable to construct the machine with the parts as shown in said l igs. JR. 215 and 30 that when the celluloid tubes or sheath: pass from rolls ltlti. under roll 10?, and the-n up and hctv-t-cn rolls low. ihev are still in a somewhat sol't condition and liable to l-ic me bent or curved in thcir ev ral changes of oircction of movcnn-nt and therefore are l able to not meet the knit and ccnt rinr-j vstop properly. or to i-x--ue from the machin in straight u'intlition. tn the three liguro-- referred to, th machine is shown as hat in;{ a frame tXitl5 l()ll 2H2 which is ro t vldcd with an opcning til at the sides ol Willi'li are ways :20!
